My Radeon X800 GTO works fine about resolusions and refreshrate by using Natit and Callistob008.

But my card was recognized as "RADEON X800 UO" ... Why?

And then, Although I used "ATIRADEON9700.kext", it didn't work for my card...no good!
Because I was not able to be supported "Quartz Extreme" on my card...

Anyone, Tell me some successful examples about "RADEON X800 GTO".

Thanks =)
